Description

  The present invention relates to an apparatus for transferring raw meat chunks to be fed to a next-stage processing apparatus in a ham manufacturing process, in which a plurality of raw meat chunks are arranged in a uniform posture. Examples of the processing device at the next stage include a filling device for shaping the raw meat mass into a cylindrical shape and filling the casing, an injector for injecting the pickle liquid into the raw meat mass, and the like.

  For example, the raw meat mass that has been loosened by the tumbling device is transferred from the rotary drum to the transfer tank and transferred to the filling device. In the filling device, one or several raw meat chunks are formed into a cylindrical shape and filled into the casing, but the operation of transferring the raw meat chunks discharged from the transfer tank to the filling device involves shaping the raw meat chunks. It needs to be transferred to the filling device in a posture suitable for the work, and it depends on human labor. However, this type of transfer operation imposes a large physical burden on the operator, and the transfer of the raw meat chunks must be performed intermittently according to the cycle time of the filling device, resulting in waste of waiting time. From the situation at the manufacturing site, it is desired to automatically transfer the raw meat chunk discharged from the transfer tank to the filling device in a posture suitable for shaping.

  The present applicant has previously proposed an apparatus that semi-automatically performs the above-described raw meat lump transfer operation (Patent Document 1). The feeding device of Patent Document 1 transports a raw meat mass formed on a shaping work table to a feed conveyor of an injector by first, second, and third conveyor devices. The first conveyor device is provided at a position lower than the shaping work table, and the third conveyor is provided at a position higher than the shaping work table adjacent to a feed conveyor of the injector. The second conveyor device is disposed between the first and third conveyor devices, and transfers the raw meat blocks inherited from the first conveyor device at the lower position to the third conveyor device at the higher position. Therefore, the second conveyor device is provided with an elevating mechanism for raising and lowering the conveyor unit between the transport surface of the first conveyor device and the transport surface of the third conveyor device.

  According to the automatic feeding device of Patent Document 1, the raw meat mass placed on the first conveyor device can be automatically fed to the injector in synchronization with the cycle time. However, the operation of transferring the raw meat chunk trimmed on the shaping work table to the first conveyor still has to rely on manual labor. This is because it is necessary to transfer the raw meat mass to the first conveyor in a state where the posture of the raw meat mass is in a posture suitable for the injection of the pickle liquid, and to send the raw meat mass to the injector. More specifically, this type of raw meat block is formed in a rectangular block shape having a longitudinal direction and a lateral direction. In order to properly inject the pickle liquid into the raw meat mass by the injector, the posture direction of all the raw meat mass needs to be aligned in one direction, such as the longitudinal direction or the short direction. However, the work of aligning the positions of the raw meat blocks has not been automated, and there is room for improvement in that respect.

The tank holder 21 is formed in the shape of a square frame having a U-shaped cross section with an open top surface and a right side surface, and the transfer tank 20 can be mounted on the bottom wall thereof. In the upper opening of the tank holder 21, a gate device 33 for adjusting the input amount of the raw meat mass M is provided. As shown in FIGS. 5 and 6, the gate device 33 includes a guide frame 35 fixed to the front and rear opposing walls of the tank holder 21, and a plate-like gate body 36 slidably guided by the guide frame 35. And a rodless cylinder (gate operating device) 37 for opening and closing the gate body 36. The gate body 36 can be opened and closed by a rodless cylinder 37 to switch between a closed position shown by a solid line in FIG. 6 and an open position shown by an imaginary line in FIG. 6. Further, the gate body 36 is stopped at an opening halfway position. Thus, the size of the opened opening can be changed.

  As shown in FIG. 5, a vertically long link fitting 24 is fixed to an outer surface of the input chute 22, and a movable link 26 supported by a support 25 of the reversing table 19 and an upper portion of the link fitting 24 are connected by a pin 27. The piston rod of the operation cylinder 23 is connected to the lower part of the link fitting 24 by a pin 28. As described above, the tank holder 21 is tiltably supported by the link fitting 24 and the movable link 26 so that the tank holder 21 is inverted and tilted around the pin 27, and the raw meat mass M in the transfer tank 20 is rotated by the rotating drum. It can be reliably fed toward 41. The support 25 is provided with a fixed chute 29 for guiding the raw meat mass M fed from the transfer tank 20 into a rotary drum 41 described later.

  The transfer tank 20 includes a tank body 32 made of a stainless steel cylindrical container having an open upper surface, and four casters 34 are fixed to a bottom wall thereof. Therefore, even when a large amount of the raw meat mass M is stored in the tank, the operator can push and move the transfer tank 20. In addition, the internal capacity of the tank main body 32 is 900 liters. As shown by the imaginary line in FIG. 2, when the tank holder 21 is switched to the standby position, the tank holder 21 is supported on the floor, so that the transfer tank 20 containing the raw meat mass M is transferred to the tank holder 21. The transfer tank 20, which can be mounted or emptied, can be removed from the tank holder 21.

  The attitude adjusting device 2 is disposed on a rotating drum 41 rotatably supported by the first base 40, a drum driving mechanism for rotating the drum 41, and an inner and outer surface on the outlet 41 b side of the rotating drum 41. An unloading conveyor 42 is provided for receiving the raw meat mass M falling in the rotating drum 41 and sending out the raw meat lump M to the first transport device 3. As shown in FIGS. 1 and 2, the first base 40 includes a base main body 43 installed on the floor surface, and a drum base 44 supported by the base main body 43. Four load cells (weight detection sensors) 45 are arranged between the drum stands 44. From the detection signal of the load cell 45, it is possible to know the input amount of the raw meat mass M to the rotary drum 41, the carry-out amount of the raw meat mass M sent from the rotary drum 41, and the like.

  The rotating drum 41 is formed of a cylindrical stainless steel body that is long on the left and right sides, has end walls on both side ends, and has circular inlets 41a and outlets 41b formed on the end walls (see FIG. 4). Four capturing blades 46 protrude from the inner surface of the rotating drum 41 near the outlet 41b. When the rotating drum 41 is rotationally driven, the capturing blades 46 capture the raw meat masses M charged in the drum one by one while rotating as shown in FIG. It is lifted and dropped onto the transport surface of the unloading conveyor 42. The capturing blades 46 are inclined so that the angle between the capturing surface 46a and the inner peripheral surface of the rotating drum 41 is about 75 degrees. In this manner, when the capturing surface 46a is inclined, after the raw meat mass M is captured on the inner bottom of the rotating drum 41, the raw meat lump M is lifted to a position higher than the transport surface of the unloading conveyor 42, and is reliably directed toward the transport surface. Can be dropped. The length of the trapping blades 46 in the left and right direction (the length dimension of the trapping blades 46 in the axial direction of the rotary drum 41) is sufficiently larger than the longitudinal dimension of the raw meat mass M (the average length of the raw meat mass M in the longitudinal direction). The raw meat mass M is lifted to a position higher than the transport surface of the unloading conveyor 42 only when all or most of the longitudinal direction of the raw meat mass M is captured by the capturing blades 46. The posture of the raw meat mass M dropped onto the unloading conveyor 42 is made constant. For example, in a state where less than half of the raw meat mass M in the longitudinal direction is captured by the capturing blades 46, the weight of the meat mass not captured by the capturing blades 46 is large. In the process of being lifted to the upper half side of the rotating drum 41, the rotating drum 41 slips off from the capturing blade 46. In addition, the length of the capturing surface 46a of the capturing blade 46 (projection dimension from the inner surface of the rotating drum 41) is substantially the same as the width dimension of the raw meat mass M (average dimension of the raw meat mass M in the lateral direction). It has been set. In this way, the raw meat chunks M are properly captured by the capturing blades 46, so that the longitudinal direction of each raw meat chunk M on the unloading conveyor 42 is aligned with the axial direction (left-right direction) of the rotating drum 41. Raw meat blocks M can be prepared.

  The drum drive mechanism is rotatably supported by a circular rolling rail 49 fixed to two places on the left and right sides of the peripheral surface of the rotary drum 41 and a drum base 44, and supports two front and rear places on the lower surface of each rolling rail 49. A total of four drum rollers 50, a motor 51 with a speed reducer, and a transmission structure for transmitting the rotating power of the motor 51 to the rotating drum 41. As shown in FIG. 4, the rolling rail 49 is formed in a concave cross section, and the drum roller 50 that engages and supports the rail 49 restricts the movement of the rotating drum 41 in the central axis direction. I have. In this embodiment, a drive pulley 52 fixed to an output shaft of a motor 51 and a belt 53 wound around the rotary drum 41 and the drive pulley 52 constitute a transmission structure (see FIG. 1). The rotating drum 41 supported by the drum roller 50 is slightly inclined downward toward the outlet 41b, and the raw meat mass M put in the vicinity of the inlet 41a gradually rotates while the rotating drum 41 is driven to rotate. Can be moved toward the outlet 41b.

  As shown in FIG. 4, the unloading conveyor 42 includes a conveyor belt 54 wound around a pair of left and right conveyor rollers, a motor 55 with a speed reducer for rotating and driving the conveyor roller at the transport end side, and before and after supporting these members. It is composed of a pair of conveyor frames and the like. The unloading conveyor 42 is arranged so that at least half of its transport surface enters the inside of the rotary drum 41, and receives the raw meat mass M dropped from the capturing blades 46 and transports it to the first transport device 3. The unloading conveyor 42 is supported by an auxiliary frame 56 provided on a second base 60 that supports the first transport device 3. Passage sensors 57 are arranged before and after the conveyor frame facing the outlet 41b of the rotating drum 41, and the number of passed raw material masses M conveyed toward the first conveyor 3 by the sensors 57 (passage situation). Detected. The passage sensor 57 is constituted by an optical sensor having a light emitter and a light receiver. When the detection light path is interrupted by the raw meat mass M, the light receiver is turned off, and when the raw meat mass M passes through the detection light path, the light receiver is turned on. State. By driving the first transport device 3 intermittently by a predetermined amount based on the detection result of the passage sensor 57, the raw meat blocks M can be aligned on the first transport device 3.

  The first transfer device 3 includes a conveyor unit 62 supported by a hinge shaft 61 (see FIG. 3) provided on a second base 60 so as to be able to move up and down, and a pair of left and right air cylinders (up and down operation) that operate the conveyor unit 62 up and down. ) 63 is provided. The conveyor unit 62 includes a conveyor belt 64 wound around a pair of left and right conveyor rollers, a motor 65 with a speed reducer for rotating and driving the conveyor roller on the transport end side, a conveyor frame 66 for supporting these members from front and rear, and the like. Be composed. As shown in FIG. 3, the hinge shaft 61 is provided in parallel with the transport direction of the first transport device 3, supports the lower rear portion of the conveyor frame 66, and the piston rods of the pair of air cylinders 63 are connected to the conveyor frame. The lower surface 66 is connected to a front portion of the lower surface by a pin 67. As described above, the conveyor unit 62 is swingably supported by the hinge shaft 61, so that the conveyor unit 62 is raised and lowered by the air cylinder 63, and the conveying surface is horizontal as shown in FIG. As shown in FIG. 3, the transfer surface can be switched to the transfer position in which the transfer surface stands upright with respect to the second transfer device 4.

  The second conveyor 4 includes a conveyor frame 70, a pair of left and right conveyor rollers supported by the frame 70, a conveyor belt 71 wound around both rollers, and a speed reducer for rotating and driving the conveyor roller at the end of conveyance. It is composed of a motor 72 (see FIG. 4) and the like. The conveyor frame 70 is supported by a third base 73, and the height of the transfer surface is set lower than the transfer surface of the first transfer device 3 and higher than the receiving position 10 a of the hopper 10. Since the left and right widths of the conveyor belt 71 are set to be substantially the same as the length of the conveyor belt 64 of the first conveyor 3 in the conveyance direction, the three raw meat blocks M transferred from the conveyor belt 64 are aligned. In this state, the hopper 10 can be received and transported to the receiving position 10a of the hopper 10.

  Next, the transfer operation of the raw meat block M in the transfer device will be described. A group of raw meat masses M crushed and loosened by the tumbling device is put into the transfer tank 20, and at this time, the gate body 36 is switched to the closed position by the rodless cylinder 37. The transfer tank 20 is mounted on a tank holder 21 that is switched to a standby position and supported on the floor surface, and is fixed to the tank holder 21 with a lock (not shown). In this state, the tank holder 21 is switched to the loading posture by the operation cylinder 23, and the raw meat mass M in the tank main body 32 is loaded via the fixed chute 29 into the rotating drum 41 being driven to rotate. At this time, the raw meat mass M that has passed over the upper edge of the gate body 36 is charged into the rotating drum 41.

  The raw meat chunks M supplied to the rotating drum 41 gradually move toward the outlet 41b, and the raw meat chunks M captured by the capturing blades 46 are lifted to the upper portion of the inner surface of the drum. At this time, the raw meat mass M trapped by the trapping wings 46 is accompanied by the trapping wings 46 and lifted to the upper part of the drum inner surface only in a state where all or most of the raw meat mass M in the longitudinal direction is supported by the trapping wings 46. Therefore, the posture of the raw meat block M can be aligned so as to be substantially parallel to the axial direction of the rotating drum 41. The raw meat chunk M supported by the trapping wings 46 and lifted to the upper portion of the inner surface of the drum is positioned such that the tip of the trapping wings 46 is located above the transport surface of the unloading conveyor 42, and then the tip of the trapping wings 46 is positioned at the transport surface. It falls down by its own weight until it is located right above, and falls on the transport surface of the unloading conveyor 42. In many cases, as shown in FIG. 1, after the leading end of the catching wing 46 exceeds the 1 o'clock position of the clock face, the raw meat mass M slips down by its own weight, and the conveying surface of the unloading conveyor 42 moves. Fall on. That is, the raw meat mass M falls from the catching wing 46 at the upper half of the inner surface of the rotary drum 41 and is transferred onto the transport surface of the unloading conveyor 42.

  When the raw meat chunks M fall onto the transport surface of the unloading conveyor 42, the output signal of the load cell 45 changes by the amount of the dropped raw meat chunks M. Therefore, the control unit 75 controls the motor of the unloading conveyor 42 as shown in FIG. 55 is started to transport the raw meat mass M to the outside of the rotary drum 41 and to the conveyor unit 62 of the first transport device 3. At this time, since the raw meat block M blocks the detection optical path of the passage sensor 57, the control unit 75 activates the motor 65 of the conveyor unit 62 in response to the OFF signal output from the light receiver, and a predetermined time has elapsed. To stop the motor 65. At the same time, the motor 55 of the unloading conveyor 42 is stopped. When the second raw meat chunk M falls onto the unloading conveyor 42, the raw meat chunk M is similarly transferred from the unloading conveyor 42 to the conveyor unit 62, as shown in FIG. Can be aligned in a straight line on the conveying surface of the conveyor unit 62.

  When the three raw meat blocks M are transferred to the conveyor unit 62, the motor 65 is stopped, and then the control unit 75 operates the air cylinder 63 in the extending direction to switch the conveyor unit 62 from the transport position to the transfer position. Then, the three raw meat blocks M on the conveyor unit 62 are simultaneously dropped on the transfer surface of the second transfer device 4. At this time, after a predetermined time has elapsed since the operation of the air cylinder 63, the control unit 75 operates the air cylinder 63 in a contracting direction to return the conveyor unit 62 to the transport posture. Further, at the timing when the motor 65 stops, the motor 72 of the second conveyor 4 is started to convey the three raw meat blocks M on the conveyor belt 71 toward the filling device 5, and from the receiving position 10a to the hopper 10 Let fall inside. Thereafter, by controlling the cylinders 12 and 16, the driving structure of the hopper 10, and the operation of the extrusion mechanism by the control unit on the side of the filling device 5, the raw meat mass M in the hopper 10 is beaten and loosened by the hammer 11.

Prepare for supply of raw meat mass M. The fact that the tank main body 32 is empty can be determined by integrating the output signal of the load cell 45 and comparing it with the total amount of the raw meat chunks M put into the transfer tank 20 from the tumbling device.

  According to the transfer device configured as described above, the group of raw meat chunks M supplied to the rotary drum 41 is captured one by one by the capturing blades 46, and the posture of the raw meat chunks M is kept uniform. Thus, it can be dropped on the carry-out conveyor 42. The unloading conveyor 42 can transport the received raw meat chunks M to the first transport device 3 and align the plurality of raw meat clumps M on the first transport device 3. Further, the plurality of raw meat blocks M on the first transporting device 3 can be transferred to the second transporting device 4 by switching the first transporting device 3 to the transfer position, and the second transporting device 4 fills the next stage. It can be transported to the receiving position 10a of the device 5 in a posture suitable for shaping. Therefore, a transfer device that can automatically feed the raw meat chunks M supplied to the rotary drum 41 to the receiving position 10a of the filling device 5 in a state where the raw meat blocks M are aligned in a predetermined posture and further aligned is obtained. Further, the operator only has to transfer the transfer tank 20 with the casters 34 between the tumbling device and the transfer device and mount the transfer tank 20 on the tank holder 21, which is inevitable in the conventional ham manufacturing process.

Relocated. According to such a transfer device, a plurality of raw meat blocks M can be transferred to the second transfer device 4 simultaneously and without disturbing the rows simply by switching the conveyor unit 62 to the transfer position by the air cylinder 63. . In addition, the plurality of raw meat blocks M arranged in a straight line on the conveyor unit 62 are stationary at the position where they are transferred to the transport surface of the second transport device 4, so that the plurality of The feeding of the individual raw meat blocks M can be accurately performed by the second transport device 4. In particular, when manufacturing a long cylindrical ham for sliced ham, a long casing is filled with three to four raw meat lumps M, but even in this case, a plurality of raw meat lumps M are aligned. Transport can be performed accurately.

  Since the tank reversing device 1 is composed of the reversing table 19, the tank holder 21 that is tiltably supported by the reversing table 19, and the operation cylinder 23 that tilts the tank holder 21 between the standby posture and the loading posture, the tank reversing device 1 is configured. By inverting the transfer tank 20 mounted on the holder 21 with the tank reversing device 1, the raw meat chunks M in the transfer tank 20 can be reliably fed to the rotating drum 41. Further, a gate device 33 is provided at the upper opening of the tank holder 21 so that the gate body 36 can be opened and closed by the rodless cylinder 37, so that the amount of the raw meat mass M to be charged into the rotary drum 41 is adjusted.

Therefore, the rotating drum 41, which is rotatably supported by the drum roller 50 and has a small rotation resistance, may be rotationally driven by the motor 51 and the transmission structure, and it is not necessary to use the high-output motor 51. And the rotary drum 41 can be reliably driven to rotate. Further, since the rotating drum 41 is rotatably supported by the drum roller 50 provided on its outer periphery, the internal space of the rotating drum 41 into which the raw meat chunks M are introduced can be opened as a circular space without obstacles. Accordingly, the unloading conveyor 42 can be arranged inside the drum without any trouble. In addition, the capturing wings 46 capture the raw meat chunks M, transfer the captured raw meat chunks M to the unloading conveyor 42, and place the unloading conveyor 42 on the unloading conveyor 42. A series of processes for transporting the raw meat mass M to the outside of the rotary drum 41 can be smoothly performed without difficulty.

  The operation of the air cylinder 63 is controlled based on the output signal of the passage sensor 57 disposed on the unloading conveyor 42, so that the conveyor unit 62 can be switched between the transport position and the transfer position. After the passage sensor 57 confirms that the raw material is aligned with the transfer surface of the first transfer device 3, the conveyor unit 62 is erected by the air cylinder 63, and the three raw meat blocks M are simultaneously transferred to the second transfer device 4.
